After sacrificing Zack and sending him to your graveyard instead of your command zone, reanimation effects like the one on Sun Titan can bring him back into play or to your hand to restart the gameplay loop , allowing you to keep stacking counters on your creatures
When you discard one or more cards this way, Borborygmos and Fblthp deals twice that much damage to target creature
Without his goofy face and Lorcanas charming art style, this card could have been nightmare fuelbut thankfully, its more giggles than screams
It is possible for a deck to have a theme and still be too strong for it
Sacrifice this enchantment: Regenerate all Werewolf creatures you control
Cards that accomplish this include Squee, the Immortal, Eternal Scourge, and Misthollow Griffin
